Change selection brush size in macro

[Josh Doe-2]

Hello,
I'm trying to change the size of the selection brush tool in a macro. I
haven't had any luck figuring out how to do it. The size seems to be set in
ij.gui.Toolbar. There is a public static int getBrushSize, but I see no
matching setBrushSize. Is there some other way that I could change the brush
size from a macro?
Thanks,
-Josh

You can set the size of the selection brush tool in a macro using

     call("ij.gui.Toolbar.setBrushSize", size);

The Toolbar.setBrushSize() method was added in ImageJ 1.41o.

You can get the current size using

     size = call("ij.gui.Toolbar.getBrushSize");

Agh, egg on my face for not checking the latest source. I was referencing
the browseable API source, which is 1.41k. Sorry for that.

But thanks for pointing it out, so glad to see you read my mind months ago!

This is stored in the brushSize member of ij.gui.Toolbar, which is
private, unfortunately.

You can play games with java.lang.reflect.Field.setAccessible(), but that
is rather dirty.

Ah, I see that I based my analysis on 1.41n.  Bad luck.

Sorry,
